Double-axis tracking bracket structure: Generally, in high latitudes, because of tracking the change of the incident angle of the sun within one day and one year, this method obviously has the highest improvement on the power generation. Comparing the annual power generation, the dual-axis tracking is 35%-40% higher than the fixed power generation. This operation mode adjusts the inclination angle of the bracket according to the change of the incident angle of the sun within one year, so as to improve the power generation .
